Max-Trak Model 180 measures and controls gas mass flow rates from 0 to 200 slpm (optionally to 400 slpm) with accuracy of ±1% FS and repeatability of ±0.2% FS. Flow body is slightly longer than 5 in. Controller meets the rigorous requirements of NEMA 6 and IP67, making it ideal for washdown environments.• Accuracy • Standard: +/- 1% of Full Scale including linearity at operating conditions • (+/- 2% of Full Scale for 180M from 201-300 slpm) • High Accuracy Calibration: +/-0.7% of reading + 0.3% of Full Scale at • calibration conditions • Dial-A-Gas • +/- 1% of Full Scale in all 10 standard gases • Repeatability • +/- 0.2% of Full Scale • Temperature Coefficient • +/- 0.025% of Full Scale per °F (0.05% of Full Scale per °C), or better • Pressure Coefficient • +/- 0.01% of Full Scale per psi (0.15% of Full Scale per bar), or better • Response Time • 300 millisecond time constant; 2 seconds typical to within +/-2% of final value • (includes settling time). Faster or slower available upon request.
